Re: Here we go again

If Apple does have some chip that will replace the G4 next year, who in here thinks that Apple will have them go more than 30% faster than the previous generation? What has been the biggest speed bump that Apple has had compared to what it replaced? Will they use dual processors, or will they just put one that is a little faster than two? Hope we dont get the usual top two getting upgraded and the bottom getting Yikesed.
What will the low end look like? Would the low end going from dual 867 to a 1gig be enough? Has Apple ever given us a speedbump that has made the low end faster than the high end that it replaces?
This is an entirely different family of processors. You can't base projected clock speed off of existing processors.
This will be a varient of the IBM Power4 processor, the PPC 970. It is a completely new processor (aside from the power4 roots).
IBM has already announced that they are targeting 1.4-1.8 GHz on a .13 micron process.
This is where you should expect initial shipments to fall.
It is a new processor though, so you have to remember that...
* it will be MUCH faster than a G4 at a given clock speed... IBM posted early SPEC scores for a 1.8GHz part that come close to the 3GHz P4 and the upcomming 1.8 GHz AMD clawhammer. PPC970 seems to run SPEC about twice as fast as the G4.
* IBM stated that the current SPECs are likely to go up... they are currently testing pre-production silicon
* IBM has recently stated that the original projections were conservative and they have hinted that they might debut at around 2GHz.
* IBM will produce these .13micron chips at a new plant that is supposed to ramp up a .09 micron process in the first quarter of this year... we may see the 970 come out as a cooler/faster .09 micron part later this year (rather than the .13 micron part they are testing now).
Anyway... I doubt that the entire Apple line would move to a new 64bit PPC at the end of this year. The 'Pro' line would go first... That would be xServe, towers, and the Powerbooks (when the chips were running cool enough)... the consumer machines probably won't follow until sometime in 2004... depending on cost, heat, yield... of the new chip.
The good news is, the cream of the G4 crop will be available for consumer machines when the 970 moves into the pro line... MOTO is _supposed_ to hit 1.8GHz with the G4 later this year...
